where \(\mathbf {1}_{[k \ne i]} \in \lbrace 0, 1\rbrace \)  is a function of \(i\) , \(k\)  which outputs 1 when \(i \ne k\) . Here \(\tau \)  represents a temperature parameter which scales the cosine similarity. In some previous works such as [1]}, loss function defined above is termed normalized temperature-scaled cross entropy loss. Figure REF  depicts a visual illustration of the proposed ST-CLR method.
